IN CASE OF EMERGENCY225
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (such as
a depleted battery), a Manual Park Release is
available.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.
WARNING!
Always secure your vehicle by fully applying
the parking brake before activating the
Manual Park Release. In addition, you should
be seated in the driver's seat with your foot
firmly on the brake pedal when activating the
Manual Park Release. Activating the Manual
Park Release will allow your vehicle to roll
away if it is not secured by the parking brake,
or by proper connection to a tow vehicle.
Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury
or death for those in or around the vehicle.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
bumpers or associated brackets. State and
local laws regarding vehicles under tow must be
observed.If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
If the key fob is unavailable, or the vehicle's
battery is discharged, refer to "Manual Park
Release" in this section for instructions on
shifting the transmission out of PARK for
towing.

Removing Wiper From Wiper Arm

5. Gently lower the wiper arm onto the glass.
Installing The Front Wipers

1. Lift the wiper arm off of the glass, until the wiper arm is in the full up position.

2. Position the wiper blade under the hook on the tip of the wiper arm with the wiper
locking tab open.
3. Insert the receiver bracket on the wiper assembly into the hook on the tip of the arm
through the opening in the wiper blade
under the locking tab. 4. Slide the wiper blade onto the arm until
motion stops, then fold down the locking
tab to secure.
NOTE:
The locking tab will not snap into place until the
blade is properly positioned on the wiper arm
hook.
5. Gently lower the wiper blade onto the glass.EXHAUST SYSTEM
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the
underside or rear of the vehicle is damaged;
have an authorized technician inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, have the exhaust system inspected
each time the vehicle is raised for lubrication or
oil change. Replace as required.

3 — Locking Tab
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing CO, refer to
“Safety Tips” in “Safety” for further informa -
tion.
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri -
ously reduce engine performance and
cause serious damage to the engine.

Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the brake system warning light
indicates system failure.
Check the fluid level in the master cylinder
when performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear.
However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only brake fluid that has been
recommended by the manufacturer, and has
been kept in a tightly closed container to avoid
contamination from foreign matter or moisture.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
AUTOMATIC TRANSMISSION
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only the
manufacturer's specified transmission fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications. It is
important to maintain the transmission fluid at
the correct level using the recommended fluid.
WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” in “Technical Specifications” for
further information. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder reser -
voir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
a open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
